ed between the tracks, in the usual slightly off center position, by theother parts referred to, as shown in Figs. 1, 2 and 3. This reducednumber of parts materially simplifies the process and labor of erection.

The'term bumper head, without more, is used throughout the specificationand claims in a broad sense to indicate generally, andregardless oftheparticular construction, those parts of the post to which the stressof impact is delivered. In the structure illustrated, however, thedetails of which are now to be described but without limitation theretoexcept where included in particular claims, instead of the customaryheavy casting, the bumper head is a light, but strong, box-structurefabricated by welding together rolled plate-steel members as best shownin Figs. 13, 14 and 15. In these figures 1 indicates the bumper faceplate, 2 and'3 side plates both cornering on the back of the bumper faceplate 1 at the outer front edge of each and welded thereto, 4 and 5inner top and bottom end abutment plates cornering on the back of theface plate at the lower front edge of each and welded theretobetween theside plates, said plates extending downward and rearward in parallelplanes, 6 a vertical brace and spacer plate having its front edge in theplane of the rear of the face plate and welded thereto and its top andbottom edges re spectively in the planes of the platesf l and 5 andwelded thereto, and 7 and 8 top and bottom cover platesoornering on andwelded to the rear of the face plate at the lower front edge of each andwelded to both of the side plates. The plates 7 and v8 may extendbeyondthe side plates and both are provided with bolt holes 9 each alignedaxially with one of the bolt holes in the other plate. The top coverplate 7may have a groovelO in each side edge for the reception of atension member, as will be hereinafter explained. All the plates arebrace plates, since they strengthen and brace the structure.

The shape and relation of the various plate members or plate pieces willbe apparent from the drawings and particularly from Figs. 13. 14 and 15.They are square-sheared and welded incornerwise relation to the back ofthe face plate which avoids the necessity of finishing their front edgeson an angle or bevelling to fit the face plate and makes it possible toreadily weld them at any desired angle. Welding fills in' the crevice,thus producing ample bearing andattachment of one section to the other.This arrangement not r 1 1ly promotes strength and lightness but makesit possible to vary the shape of the head at will to suit particularcompression members or other special conditions. The readiness ofadaptability thus obtained is in dicated by the modified construction ofthe.

head shown in Figs. 17, 18 and 19, wherein the headshown in the otherfigures which is adapted to freight cars, is extended forward to giveadditional clearance to the air hose and steam connections as used inpassenger cars and is provided with means for returning the coupler barto center, which is desirable, since the ends of passenger cars, as iswell-known, have a much longer swing than the ends of freight cars. Inthe three figures referred to, spacer, brace plates 11, shown asidentical horizontal plates, with curved front edges, equally spacedvertically are welded to the front of the face plate 1 and to the rearof the horizontally concave strikerplate 12. Side cover plates 13, 14:may be welded to the front of the face plate 1, the rear'of the plate12, and to the adjacent ends of the space plates. The various platesused in the bumper head and its extension may be of any appropriatethickness, but I have found that face plates of 1 4 thick ness and otherplates thick serve the purose. p The bumper head as thus formed providesa box opening downward at the rear and of suitable dimensions to receivethe upper front ends of both the compression members 15 whicharepreferably H beams, since beams of this cross section are much stifferthan channels or members of other cross section. As indicated in Fig.13, the forward ends of the H-beams 15 abut respectively on the adjacentrear edges of the plates 4:, 5. The flanges of the H-beams are incontact at the top with the underside of the cover plate 7 and at thebottom with the upper side of the cover plate 8; their outer edges arein contact with the inner sides of the side plates 2, 3 andthe innerfront corners of the flanges of the left hand H-beam are in contact withthe inner edges of the right hand H-beam, so that the said ends of theH-beams occupy the said space in the bumper head across the head and theparts are maintained in right relation and the structure well braced.Separate housing'of the ends of the H-beams is unnecessary, thearrangement described being preferred. .While H-beams are for-reasonsstated particularly desirable as compression members, they do notreadily lend themselves to such use owing to the difficulty ofassociating them in proper thrust contact with the bumper head andparticularly with the rails and road bed. The way in which theirrelation to the bumper head has been taken care of has just beendescribed, the other part of the problem has been solved in the mannernow to be stated.

Referring particularly to Figs. 9 to 12, the compression track fixtureswhich are substantially the same but reversed are built up out of plateor plate-like elements, as indicated in Fig. 9, which illustrates theleft hand compression fixture showing separated the'ele- Inentsconsidered most desirable along with the end of the adjacent H-beam,which is i0 y y a i inclined to suit/the incline ofthe topof the CEBU ofthe r'ail and the flange 21secure the comto be 'vveldedntothetrackfixture to form a composite compression unit.

the angle ofthe bar and the resulting erevices arefilled in with fusedsteel in the Welding of theparts together. The bar is thus weldedonbothfaces of theplate. The tensionstructiue is designed to transmitthe strainto a heavy cross bean139, extending between the tles acrossthe track andseatrng under the respective rails as in my pendingapplication, Ser. No. 390,417, filed September 5, 1929, whereinspecifically different structure having common characteristics is shownand broadly claimed. The plate 37 has welded thereto a spacer pad 40,which seats on the top of the cross beam 39, thus locating the plate 37in a horizontal plane. In the construction illustrated in the. saidfigures, the tension structure includes means for receiving andsurrounding the cross beam. This is a U-bolt 41 whose closed end havingweldedtherein a filler half disc 42 seats on the underside of the crossbeam, the bolt being provided with nuts 43 and having its legs at theends of the spacer pad 40. The railattachment flange 38 of the tensiontrack fixture has welded thereto pads 44 which seat 011 the inside ofthe rail web. Said flange, pads and web are drilled to provide holes forattaching bolts 45, which pass also through correspondingly located boltholes in clamp bars46, similar to the clamp bar shown in Fig. .9 butshorter and having only two bolt holes and are secured by nuts 47. Lugs48 welded to the top flange of the cross beam 39 near 'each end of thebeam serve as abutments for the inner edge of the respective plates 37to prevent the plates from being drawn toward each other on bumperimpact. It will be apparent that the composite tension and track fixturememberas well as the composite compression and track fixture member canbe handled as a unit. The tension track fixtures are located directlyopposite to each other in the track and serveto correctly locate andanchor the tension cross beam and to transmit'stress of bumper impactthereto and also to the respective rails to which the plate members 37are attached. The tension bars are welded to the track fixture plate ata point between that at which the tension structure embraces the crossbeam (U-bolt) and that at which the tension struc ture is secured to therail (bolts 45), so that the pull of the tension member distributes partdirect to the rail web and part to the beam 39 and rail base.

A slight modification of'the tension con nection to the rail and roadbed is illustrated in F 7, which represents this connection applied to agirder trestle, such as is used for coal pockets and wherein an I-beam49 underlies each rail. Here, also, the tension bar 33 passes throughand is welded to the base plate 37 of the tension track fixture, whichhas the pad 40 and the rail attachment flange 38 and is secured to therail web in the manner described in connection with Figs. 1 to 6. Itwill be observed, however, that plate 37 is extended further inwardtoward the center of the track to clear the flange'of the I-beam andthat the lug 5O welded to the top of the cross beam 39 is extended underthe adjacent flange of the I-beam and has its upper. surface inclined tocorrespond with. the under surface of the I-beam flange. It will be seenalso that the lug 50 extends further above the upper side of the crossbeam 39, as itmust, in order to oppose the inner edge of the plate 37.The U-bolt is also necessarily longer and is located just beyond'the pad40.

Another modification of the tension connection to the track is shown inFig. 8, wherein the closed end of the U constituted by the U-bolt isomitted and upright bars'or legs 51 are welded to the front and back ofthe cross beam 39, filler blocks 52 of substantial width being welded tothe respective channels and to said legs. The rest of the structure isas above described in connection with the form illustrated by Figs. 1 to6.- No attempt has been made to exhaust the possibilities in designingmodified forms of the tension connection, and it is to be understoodthat, except as may be specified in particular claims, the invention isnot limited to the details shown. The modified construction illustratedin Fig. 8 has the advantage of requiring less excavation and it or someother arrangement, preferably of welded parts, which does not extendbelow the bottom of 'the tension cross beam but which secures it withrequisite strength to the rest of the tension structure may be employed.--Tl1is post without alteration fits any rail from 5 to 7 high. -Bymodifying it slightly, it can be constructed to suit lower or higherrails. The parts are so light and so readily handled that the simpleoperations incident to setting up the post can all be performed by oneman.
